Description

[Technical field]

[0001] The utility model relates to the technical field of flue gas pollutant treatment and electric dust removal, in particular to an anode plate vibration transmission device with a large contact area. [Background technology]

[0002] Electrostatic precipitator is the mainstream equipment for removing dust from industrial flue gas. Its core components mainly include the discharge cathode wire and the dust collecting anode plate. The anode plate is usually called the dust collecting plate or the precipitation plate. Its function is to capture charged dust. Through the impact and vibration of the vibration mechanism, the plate will vibrate or shake, and the dust attached to the surface of the plate will fall into the ash hopper in the form of flakes or clumps, so as to achieve the purpose of dust removal.

[0003] The existing anode plate-shaped vibration cleaning method of the electrostatic precipitator is generally to set an opening and a clamping plate at the bottom of the anode plate, and then transmit the vibration acceleration to the anode plate through a vibration device. Since the use instructions of the anode plate generally require 30 years, and the thickness of the anode plate is generally only 1.2-1.5mm, long-term vibration can easily cause the bottom of the anode plate to wear, so that the vibration transmission position cannot be effectively contacted, resulting in the anode plate vibration acceleration not meeting the requirements, affecting the anode plate cleaning effect and causing the dust removal efficiency to decrease.

[0004] In order to improve the anti-vibration performance of the anode plate, "A reinforced anti-vibration anode plate" (patent number CN202120888082.3), "A repair method for an electrostatic precipitator anode plate" (patent number CN202110102664.9) and "A reinforcement structure for an electrostatic precipitator anode plate" (patent number 202223537945.6) proposed adding reinforcing splints at the fixing holes of the anode plate. However, this method has problems such as large local stress and the vibration holes are still easy to be damaged. Structurally, it is only reinforcement, and none of them proposes the essential problem of reducing local stress and fatigue. [Contents of the utility model]

[0006] To achieve the above-mentioned purpose, the utility model proposes an anode plate rapping and transmission device with a large contact area, comprising two clamping plates, a plurality of concave sleeve bodies and convex sleeve bodies are arranged between the two clamping plates, the concave sleeve bodies and the convex sleeve bodies correspond to each other one by one and both clamp the corresponding concave and convex holes on the anode plate, the rear end of the concave sleeve body is provided with a groove matching the concave and convex holes, the front end of the convex sleeve body is provided with a protrusion matching the concave and convex holes, the concave sleeve body around the groove and the convex sleeve body around the protrusion cooperate to clamp the anode plate, and an impact head is arranged between the rear ends of the two clamping plates.

The concave and convex holes are clamped by the cooperation of the grooves and the protrusions, and the concave sleeve body around the grooves and the convex sleeve body around the protrusions cooperate to clamp the anode plate. The contact surface of the vibration acceleration transmission position at the bottom of the anode plate is large, and the vibration force transmission effect is good during vibration cleaning, which is especially suitable for the electrostatic precipitator with an ultra-high electric field height of 15 meters to 16.4 meters in height of the anode plate;

[0013] 2. Solve the problem of wear of the fixed position at the bottom of the anode plate caused by repeated vibration for a long time, increase the contact area, and achieve good vibration force transmission effect during vibration cleaning;

[0014] 3. The modification of the existing electrostatic precipitator is simple. It only requires the modification of the vibration transmission device at the bottom of the anode plate. The modification cost is low, the construction period is short, the modification adaptability is good, and it has the market potential for large-scale promotion and application.
